[Firebird-devel] IResultSet::isEof() and isBof()

2020-03-18 Thread Dimitry Sibiryakov 

  Hello, All.

  What these methods are supposed to return before call of fetchNext()?
  What they should return if the result set is empty after fetchNext()?

  Ok, though ADO and others used to set them both to true...

  And if fetchFirst/Last() returned RESULT_NO_DATA, what should be the values of the 
flags afterward?
